Embodiment 1
[0043] A preparation method of triterpenoids in bristle grass, comprising the steps of:
[0044]Step (1), extraction of extract: crush the dry aboveground part of bristle grass to 30-50 mesh, use 70% ethanol aqueous solution as the extraction solvent, extract twice at room temperature, each time for 6 hours, filter the extract, Concentrate the filtrate under reduced pressure to obtain the extract;
[0045] Step (2), silica gel column chromatography: apply the extract obtained in step (1) to silica gel column chromatography, the column silica gel is 200-300 mesh, and carry out gradient elution with a mixed organic solvent of petroleum ether and acetone; collect each gradient The gradient eluate was concentrated and monitored by TLC, and the same parts were combined to obtain seven parts A1-A7;
[0046] Step (3), gel chromatographic separation: use a mixed organic solvent of chloroform and methanol at a volume ratio of 1:1 as the eluent, and use gel chromatography to elute part...
Embodiment 2
[0048] A preparation method of triterpenoids in bristle grass, comprising the steps of:
[0049] Step (1), extraction of extract: crush the dry aboveground part of bristle grass to 30-50 mesh, use 95% ethanol aqueous solution as the extraction solvent, extract at room temperature 4 times, each time for 10 hours, filter the extract, Concentrate the filtrate under reduced pressure to obtain the extract;
[0050] Step (2), silica gel column chromatography: apply the extract obtained in step (1) to silica gel column chromatography, the column silica gel is 200-300 mesh, and carry out gradient elution with a mixed organic solvent of petroleum ether and acetone; collect each gradient The gradient eluate was concentrated and monitored by TLC, and the same parts were combined to obtain seven parts A1-A7;
[0051] Step (3), gel chromatographic separation: use a mixed organic solvent of chloroform and methanol at a volume ratio of 1:1 as the eluent, and use gel chromatography to elute ...
